Apps

This directory contains the apps we use for testing Expo. Do not add new apps to this repository. Each app increases our maintenance costs and complexity of different packages in node_modules that interact with each other in subtle ways. To keep this repository healthy and maintainable, we need to minimize the number of apps we have.

• bare-expo

  An Expo app that can load the Test Suite and Native Component List's JS.

• jest-expo Mock Generator

  An app that uses reflection to generate Jest mocks for native modules. Eventually we can remove the need for this once we have a JSON schema for each module definition (Turbomodules) and generate the Jest mock from the JSON schema.

• Expo Go

  The UI for the Expo Go client.

• Native Component List

  A showcase of the components and APIs in the default Expo preset.

• Sandbox

  A project excluded from Git where you can try out things locally.

• Test Suite

  End-to-end tests that run on Expo.

Ideally, we'd just have one directory with a customized project with Xcode and Android Studio projects. The project would have different build targets and include different native modules. We'd have a build target each for the Expo Client, Test Suite (customized, with support for APIs like payments), and Native Component List (customized). These would be the only apps in the repository.
